1. GENERAL DESCRIPTION
The W561xxx is one of the derivatives of the BandDirectorTM familiy. It consists of a 4-bit µC, two
voice synthesizers, one 4-track PCM-Melody generator, and one shared ROM.
The muti-tasking operation for voice synthesis and 4-track PCM-Melody generation is implemented by
dedicated H/W that can output the speech voice in parallel with the background music. With the 4 bit
kernel, which can execute instructions of up to 12 KIPS (Kilo-Instructions Per Second), and high
quality dual speaker output, you will be amazed at the possible applications. W561xxx provides you
with a total solution in one chip.
In addition, the W561xxx's user-friendly development environment can effectively reduce your design
period and help you easily tool your projects by yourself with the ICE and emulation kit.
There are 10 kinds of W561xxx IC bodies (see table below).

Note: The voice durations are estimated by 8.0 KHz sampling rate
Possible applications are:
• Programmed voice synthesis with background music or speech
• I/O interactive voice synthesis to accompany background music or speech
• Demo of music songs with possible dynamic timbre/tempo changes during playback
• Q&A games
• Edutainment toys
2. FEATURES
• Multi-engine processor parallel management with µC, speech and PCM Melody
− µC // (Synthesizer1 or 4-track PCM-Melody) // Synthesizer2 (//: in parallel)
− µC, with basic ALU, 64-nibble RAM (including 8 working registers) and an 8-bit timer
The W561&W562 user RAM initialization value is not constant. It is random. So, user must
initial constant value.
− Synthesizer1 capable of voice syntheses with Sample rate @4.8/6/8/12 KHz
− Synthesizer2, same as synthesizer1
− 4-track PCM-Melody with total 16 Kbyte Timbre table, which can store up to 16 kinds of
timbre samples.

− The on-chip ROM is shared among program, voices and melody notes
− ICE & ROM chips use different Rosc. Rosc for mass production should check “W561 Freq vs
R.pdf” file for more details.
• Wide operating voltage range: 2.4 to 5.5 volts
• Low power consumption (VDD = 5 Volt)
− Standby current < 2 µA
− Operating current (no load with ring oscillator) < 1 mA
• Main oscillator: Crystal/ Ring oscillation selectable by pin option
• Input/ Output port
− Port for input only: 1 port/4 pins
− Input/ Output ports: 2 ports/8 pins
− Port for output only: 1 port/4 pins
− Can offer a direct row and column matrix of up to 72 (8 × 9) keys
• Interrupts
− Internal interrupts: Timer
− External interrupts: TG (port 0, port1), POI (Power On Initialization)
− Priority: POI > TG > Timer
• DAC1/2 provided for stereo voice output
• Melody + Voice output for DAC1
• TG interrupt provided
− Shared TG interrupt for Port0/Port1 input.
− Global TG interrupt enable controlled (bit3 of the IER register)
− Individual interrupt enable controlled (PER0 and PER1 registers)
• Built-in 8 bit programmable down count timer
− One of two internal clock frequencies can be selected
− Desired Timer interval = (preset value +1) × 1/FT
(FT: 32 Hz or 32 KHz dependent on the bit0 of the MODE register, at Fosc = 3 MHz)
• Powerful instruction set:
− Arithmetic: ADD, ADDC, SUB, SUBC, INC, DEC, SETB, CLRB
− Logic Operation: AND, OR, XOR, NOT
− Shift & Rotate: RORC, ROLC, SHRC, SHLC
− Date move: LD, LDR, MV
− Branch: JP, JB0, JB1, JB2, JB3, JZ, JNZ, JC, JNC, JBZ1, JBZ2, CJNE, CJE, DJNZ, DJZ
− Subroutine: CALL, RTN, RTI
− Others: NOP, END, EN INT, DIS INT, PLAY CH1, STOP CH1, STOP CH2
• 8-level STACK shared by CALL, Timer, Synthesizer and TG
